Shutdown Quiets NASA, So Space Station Astronauts Enjoy View : The Two-WayWith the space agency largely grounded, employees Karen Nyberg and Mike Hopkins continue to orbit 250 miles above Earth aboard the International Space Station. While it's not clear they have all that much to do, their Twitter feeds show they may be getting creative — and perhaps a bit bored.

But there are two NASA workers who can't leave the office, at least not without great expense to the taxpayer. Astronauts Karen Nyberg and Mike Hopkins are orbiting some 250 miles above Earth aboard the International Space Station. They're in touch with mission control, but it's not clear they have all that much to do.

Intriguingly, while nearly all of NASA's Twitter feeds are offline, Nyberg and Hopkins have both tweeted since the shutdown began. And their tweets hint that they might be just a weensy bit bored:
